Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Aircraft Mechanics and Service Technicians

Maintenance of F-35 structures, composites, hydraulic systems, pneumatic systems, and landing gear directly overlaps civilian aircraft airframe work.

How to prepare: Gather records of your airframe maintenance experience for FAA evaluation toward the Airframe rating. The experience route requires 18 months appropriate to one rating or 30 months concurrently covering both Airframe and Powerplant, plus written, oral, and practical tests; approved training routes also exist, and the supplied duties do not establish Powerplant experience.

What the civilian work involves
  • Read and interpret maintenance manuals, service bulletins, and other specifications to determine the feasibility and method of repairing or replacing malfunctioning or damaged components.
  • Examine and inspect aircraft components, including landing gear, hydraulic systems, and deicers to locate cracks, breaks, leaks, or other problems.
  • Maintain repair logs, documenting all preventive and corrective aircraft maintenance.

Aircraft Structure, Surfaces, Rigging, and Systems Assemblers

Aircraft structure and composite repair experience transfers to inspecting and reworking aircraft parts and assemblies in production.

How to prepare: Practice interpreting aircraft assembly blueprints and specifications to identify part relationships and assembly sequences.

What the civilian work involves
  • Read blueprints, illustrations, or specifications to determine layouts, sequences of operations, or identities or relationships of parts.
  • Inspect or test installed units, parts, systems, or assemblies for fit, alignment, performance, defects, or compliance with standards, using measuring instruments or test equipment.
  • Adjust, repair, rework, or replace parts or assemblies to ensure proper operation.
